SPECrFICATIQN forming part of Letters 4Patent No. 315,348, dated Apr'n 7, 1885.

Application filed July 26, 1884. (No model.)

To all whom t may concern: d v Be it known f that I, GEORGE W. SHARER, a citizen of the United States, residing at Terre Haute, in the county of Vigo and State of Indiana, have invented certain new and use-A ful Improvements in Driers; and I do hereby declare the following to be a full, clear, and, exact description of the invention, such as will enable others skilled in the art to which it appertains to make andl use the same. Q

My invention relates to driers for all kinds of articles, but .particularly to that class in which brick, pottery, tile, lumber, and simil lar objects are deprived of their moisture.

The object ofthe invention is to make a drier that will combine cheapness in construe#` tion and utility in the arrangement of parts, so that in working theV drier the operator can take every advantage to facilitate his work.

My invention therefore consists of construcl tions and combinations, all as will hereinafter be described and claimed, reference being had to the accompanying drawings, in which- Figure l represents a perspective view, of my improved device;` Fig. A2, a longitudinal section; Fig. 3, a vertical section throughthe chimney, breaching, and flue-A9. The `side walls are also shown in section on a line through chimneys a.V .Fig. `4C is appartial plan and section, the left-handy side' showingv a section through the lflue Aandfu'rnace, and the righthand side showing the lfloor of drying-chamber in elevation and the platform' broken away. l'

A represents the ldrying-chamber; B, the furnace; C, the distributing-vault of the furnace; D, the airpassage; E, the chimney, and

-F the breaching connecting the, chimney and drying-chamber.v The 'drying-chamber A is of oblong shape, and may be between sixty and one hundred feet in length, from five and one-half to six feet in width, and four and one-half feetin height.

Itis obvious that variations from these dimensions can be made without departing from my invention; but those stated are preferred, as I'have found by actual practice that they produce the desired resnlt.- The side walls,

a, and belowwith flueAbeneath the floor `of the chamber.

a', so that the side' walls will be heated, and thus prevent the articles in thechamber and nearest said wall frombeingchilled, as would The flue A2 is dividedinto several longitudinal smaller fines, a2, the outer y ones of which communicate directly with flues l be the case if this provisionfwere not made;

or, Vin other words, it enables the operator to keep the chamber at an even temperature, as the `j heated side walls protect the chamber from lateral radiation. y drying-chamber is the top wall of the flue A?,

' l which is made of brick or other suitable material, covered with a .thin layer of cement to` keep the smoke, sparks, andfiame out of the The bottom of the i I,drying-chamber, and` at the same time prei sent a surface that will rapidly radiate the heat.

Itis obvious that the bricksgcould be cov-v ered withmetalor other substance and pro-` The iioor of thedryduce the same result.

ing-chamber may be` leveLor` slightly in-` clined from therear end to a point near the front end, where it terminates in an opening,

flue 4A2 at this point is deflected obliquely to the distributing -V vault, and its upper wall servesas part of the bottomof the air-passage D. This passage is formed above the tinuation of the bottom of the drying-chamber so@ furnace, audits upper wall,Dl,forms a confromj the opening D', whichis bridged by a track extending through the `drier and terminating at any suitable pointfor the operation of the carriages A", that contain the material to be dried. The passage D is preferably divided y which can be made to register with the openings in the plate, so that the amount of air entering l the passage D can be regulated. The airentering through these perforations absorbs the heat radiated from the furnace and iiueA'l,

and enters the drying-compartment through .l 7 S D', `which will hereinafter be described. The

opening D as a hot-blast, thereby preventing Y A A', of the` chamber are hollow to form injury to the articles being dried, as would be, rc'o.

F5o ilues c', communicating above with chimneys the case if the blast were cold. It also prevents the' ware at the endk o i' the chamber nearest the furnace from becoming overheated and injured, as would be the case if no air vi were used. Each end of the furnace is provided with a door, A and A, which may move vertically or swing outwardly for thev admission and exit of the'cars. At the rear end is an opening, D3, which communicates with the breaching F. Infront of this opening D:i is a pendent swinging door, A7, having its lower end near the bottom of the drying-chamber, so that `thehot air which enters through opening D', and by reason of its lightness rises in the'chamber, will force the heavier vapor out of the chamber before it can make its exit beneath the door. In this way the door retards the heated air and also prevents the article near the bottom from being dried too rapidly by the heat radiated from the flue A. The door AT is preferably pivoted by its upper end, so that when the cars have been pushed into the chamber it will automatically fall in place and forms with door AG a passage, A8, forl the escape of vapor into the breaching. This passage A8 also serves to protect the articles from being chilled when door A6 is opened forthe admission of another car or for other purposes. To still further protect this end of the drying-chamber, a transverse flue, A, in which the flue A2 terminates, is placed below the bottom of passage AS. This flue A" is provided with a soot-chamber, a, provided with a suitable opening for the withdrawal of the soot when a sufficient quantity has collected. One end of the flue communicates with the chimney E, placed at one side of the dryingchamber on a line with the breaching F, which opens therein. Ihe chimney is provided with a partition, F, which does not extend quite to the top. The products of combustion pass up one side of the partition, and the suction caused by their passage draws or sucks the vapor through the breaching, and thus accelerates the draft through the drying-chamber.

The furnace, as before stated, is below the front end of the passage D. For a dryingchamber of {the dimensions above mentioned the grate-surface is preferably four by two and one-half feet. rlhe rear end is elongated to the full width of the drying-chamber to makethe heatdistributing vault C, with which, as before stated, the flue A2 is connected, and enters it about ten or eleven inches above the grate-level, leaving a chamber, c, above for the products of combustion. The top of the vault is provided with a fire-clay tile, c', surmounted by alayer of brick. The furnace and flue are also provided with similar tile, b and b', which radiate the heat into passage D, where it is absorbed by the air.

In the above description it will be noted that only one drying-chamber has been described. VVhen it is desired to use more than one, they may be advantageously separated by a thin Wall, A1", which will be readily heated by the hot air. If more than one dryingchamber be used, the breaching can be made with a sufficient number of passages to carry off the vapor from each chamber separately.

Upon inspection of the drawings it will be seen that the bottomjof line A2 is on the groundline; also the bottom of the passage D, the top of which is on the same plane as the bottom of the drying-chamber. By these means the operation of loading and unloading the cars is facilitated, as the operator can load the cars without having to elevate the material to any considerable height. By placing the furnace vbelow the ground level and beneath the passage D, the top wall of which serves as a platform, the operator is protected from the heat which otherwise would arise and make his position uncomfortable.

'Ihe operation of the device is as follows: After the re has been started, air is heated in passage D and passed into the drier, where it is further heated by the radiation from the bottom and side walls. The loaded cars are now pushed in at the rear end at such periods as may be deemed necessary. 'Ihe material on the car first put in will necessarily be dried the rst, as itis constantly advancing toward the hottest or dryest part; or, in other words, the hot air entering the front end of the dryingchamber attacks the front car first and gathers vapor which more or less reduces the temperature as it advances toward the rear end,

where it escapes under the hanging door into the breaching. As soon as the contents of one car have become dried,the latter is drawn out at the front end and another car pushed in at the rear end. By this means I am enabled to keep the drier in continuous operation.

Vhat I claim as new isl. In a drier, the combination of a dryingchamber having an inlet and outlet for air between its ends, a furnace having a ue which forms part of the bottom of the drying-chainber, and an air-passage above the furnace, its upper wall forming a continuation of the bottom of the drying-chamber and having its outlet within said drying-chamber, substantially as described.
